Reduction of NOx in Lean Exhaust by Selective NOx-Recirculation (SNR-Technique) Part I: System and Decomposition Process

Abstract
The SNR-technique is a new NOx aftertreatment system for lean burn gasoline and diesel applications. The objective of SNR is NOx removal from lean exhaust gas by NOx adsorption and subsequent selective external recirculation and decomposition of NOx in th
